Oxygen isotopic ratios of some Himalayan glaciers

Abstract

6'*0 in ice cores taken from two temperate glaciers, Changme-Khangpu (CK) and Nehnar. located in the eastern and the western Himalayas respectively, and in fresh precipitation and surface ice at different altitudes on the Changme-Khangpu glacier has been measured. The fresh precipitation in C K has 6I8O in the narrow range of-19 f 2% which is similar to the ice core values. 6180 and dust concentration in Nehnar core is found to be variable. The 6IRO values lie in the narrow range of-9.5 f 1 % in the upper 46 m section and the fluctuations increase in the 66-102 m section of the ice core.
